ABSTRACT

The present invention is a bag with easy access for cleaning and aerating comprising: a main body defining the bag; a primary opening on the top side that is selectively closed having a first fastening mechanism for providing access to an interior compartment within the main body; a secondary opening covered by a flap on at least one side that is selectively closed having a second fastening mechanism for providing access to the interior compartment for cleaning by removing any collected dust and debris from the interior compartment; and a flexible interlocking grid portion with a plurality of apertures positioned immediately beneath the flap and attached on the periphery of at least one side for removing the collected dust and debris through the plurality of apertures while shaking the bag after opening the flap.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to bags, and more particularly to a bag that is capable of carrying contents susceptible to collecting debris, dust, sand and/or dirt.

2. Description of Related Art

Athletic equipment bags, duffel bags, tote bags, backpacks, hiking bags, and other types of bags are crucial in carrying and transporting all kinds of contents from one place to another for daily activities. These types of bags collect dust, dirt, sand, and debris from activities in which we participate on a daily basis such as carrying food items, carrying baby's foods, playing sports, lying on the beach, carrying dirty shoes, and generally collecting dust from everyday use. The undesirable feature of the bags is that all the contents need to be taken out in order to clean out and empty the dust, dirt, sand, and/or debris collected at the bottom of the bag which have accumulated over time or easily collect from one single activity. For example, tote bags used while spending time at the beach collect a lot of sand when towels are put on the sand, then back in the bags. Another example is collecting dirt and soil from golfing, playing baseball, playing softball, or playing other types of sports because the shoes, clothes and sports equipment pick up dirt and soil. These items with dirt and soil are directly inserted into the bags for transporting them back home. Mothers always carry baby's items such as crackers, foods, and other soiled items in a bag on a daily basis. It is very difficult to clean out crumbs from the bottom of the bag without taking out the contents completely and turning the bag upside down. More often than not, people are too busy with their lives to remove the contents from the bag to clean out the dirt and soil collected at the bottom of the bag on a regular basis. Because sports bags contain heavy items such as bats, baseball gloves and dirty shoes, it is not desirable to empty out the contents to remove the collected dirt and soil from the bottom of the bags.

In order to rectify this problem, the present invention allows cleaning and aerating the bottom of the bag without having to take out all the contents from the bag. The present invention overcomes these and other known disadvantages with existing athletic bags, duffel bags, tote bags, sports bags, backpacks, hiking bags, and other types of bags which are susceptible to collecting much dust, dirt, crumbs, sand, and soil from everyday activities.

DETAILED DESCRIPTION OF THE INVENTION

Exemplary embodiments may be better understood with reference to the drawings, but these embodiments are not intended to be of a limiting nature.

Referring now in detail to the drawing figures, FIGS. 1-6 illustrate a duffel bag 100 in accordance with the present invention. The duffel bag 100 generally defines a top 135, a bottom 155, a front side 105, a rear side 190, handles 125 attached at the front and rear sides 105, 190, opposing right and left sides 150, 140, a flap 165 at the bottom 155, a primary opening 120 at the top 135, and a secondary opening 115 at the bottom 155. The bottom side 155 of the bag 100 with the flap 165 connects to the front side 105, rear side 190, right side 140, and left side 150 at the front bottom edge 107, rear bottom edge 193, right bottom edge 143, and left bottom edge 153. An interior compartment 175 is formed on the inside of the bag 100 in which various contents can be carried. As the primary opening 120 is selectively closed preferably using a zipper 195 for providing access to the interior compartment 175, the secondary opening 115 on the bottom 155 is also selectively closed preferably using a zipper 195. However, the secondary opening 115 is not limited to just the zipper 195, but to any type of opening and closing means that performs the same functionality such as hooks, snaps, velcro, and other similar fastening mechanisms. The secondary opening 115, outlining the right, front and left bottom edges 143, 107, 153, that is selectively closed or opened preferably using a zipper 195 for providing access to the interior compartment 175 can be accessed from at least one side selected from the right side 140, the left side 150 or the front side 105. More specifically, the zipper 195 can be opened by holding and moving a zipper tab 197 from at least one bottom edge selected from the right bottom edge 143, the left bottom edge 153, or the front bottom edge 107 wherever the zipper tab 197 is sitting after closing the secondary opening 115.

FIG. 2 illustrates a side view of the duffel bag 100 wherein a right side 140 of the duffel bag 100 is shown with its front and rear sides 105, 190. The front side 105, rear side 190, right side 140, and left side 150 are joined along the edges by a flap 165 at the bottom 155, more specifically, at the bottom edges of the bottom side 160. The side view of the duffel bag 100 also illustrates the secondary opening 115 that is selectively opened or closed using preferably a zipper 195 on the bottom 155. More particularly, the right bottom edge 143 is shown to have the zipper 195 even though other types of closing and opening means can be utilized. The zipper 195 is shown to be closed on the right bottom edge 143. Similar to the right side 140, the left side 150 (not shown in this FIG. 2) is symmetrical so that the secondary opening 115 extends to the left bottom edge 153. The secondary opening 115 is selectively closed and opened preferably by the zipper 195 that extends from the left bottom edge 153, through the front bottom edge 153 and to the right bottom edge 143. The zipper 195 extending three-fourths of the bottom side 155 allows any user to closably open the flap 165 completely while one-fourth of the bottom side 155 with the flap 165 remains permanently attached to the rear bottom edge 193 as shown in FIGS. 3-4. Alternatively, the secondary opening 115 is on the bottom side 160 wherein the flap 165 is attached to at least one edge of the bottom side 155, and the zipper 195 detachably connects the flap 165 to at least one other edge of the bottom side 160.

FIG. 3 illustrates the flap 165 on the bottom side 160 in a semi-open position whereby the interlocking grid portion 170 is displayed with the contents within the interior compartment 175. FIG. 4 further illustrates the flap 165 in an open position with the secondary opening 115 being completely open. The flap 165 at the bottom side 165 is depicted as being attached to the rear side 190 at the rear bottom edge 193 while the zipper 195 is attached on the right bottom edge 143, front bottom edge 107, and left bottom edge 153 for accessing the secondary opening 115. Immediately beneath the flap 165 that basically covers the entire bottom side 160, the interlocking grid portion 170 on the inner side of the bottom side 160 is illustrated in FIG. 4. The interlocking grid portion 170 is strong enough to retain the contents within the interior compartment 175 while releasing any collected dust, debris, soil, dirt and other small items at the bottom side 160 through the grid portion 170 with a plurality of apertures. The bag 100 can be held by the handles 125 while shaking and releasing any collected dust, debris, soil, dirt and other small items through the plurality of apertures of the grid portion 170. The interlocking design allows the bag 100 to support any internal contents within the bag 100 in the interior compartment 175 while the flap 165 is held open and the bag 100 is shaken to release the collected dust, debris, soil, dirt and other small items through the plurality of apertures of the grid portion 270. The interlocking grid portion 170 with the plurality of apertures is flexible and has sufficient strength to support the contents which the bag 100 is intended to hold, without closing the flap 165.

The secondary opening 115 covered by the flap 165 on at least one side is selected from the group of the right side 140, the left side 150, the front side 105, the rear side 190, and the bottom side 160, that is selectively closed using a second fastening mechanism, such as a zipper, hooks, snaps, velcro, or similar means, for providing access to the interior compartment 175 for cleaning by removing any collected dust and debris from the interior compartment 175 without having to remove the internal contents from the bag 100 through the primary opening 120, wherein the at least one side has edges and the flap 165 has an interior side and an exterior side.

The interlocking grid portion 170 defining a plurality of apertures, the grid portion 170 is positioned on the interior side of the flap 165 and attached to the main body at the periphery of the secondary opening 115, for removing the collected dust and debris through the plurality of apertures while shaking the bag 100 after opening the flap 165. The interlocking grid portion 170 may be permanently attached to the main body at the periphery of the secondary opening 115 or removably attached to the main body at the periphery of the secondary opening 115 via a third fastening mechanism such as a zipper, hooks, snaps, velcro, or other similar means. The interlocking grid portion 170 illustrated in FIGS. 3-4 is generally flexible and made from plastics so that the entire bag 100 may be folded and compressed when the bag is not being used. The interlocking grid portion 170 is preferably made of high tenacity, high molecular weight, polyester yarns that are woven, reinforced in an interlocking grid design and further coated with polyvinyl chloride (PVC) for providing damage protection and durability for long-term and rigorous use of the duffel bag 100 over a long period of time. The interlocking grid portion 170 can be made out of other similar materials such as nylon, vinyl, polymers, or synthetics as long as the material provides strength and durability to endure long-term and rigorous use of the bag 100 containing heavy sports equipment and other items of similar weight whether having a rigid or a flexible form. Other materials may be utilized to provide the same functionality. The coating of PVC can also be substituted with other types of thermoplastic polymers or plastics such as polyethylene or polypropylene to provide biological resistance, waterproof protection, chemical resistance, ultra violet resistance, corrosion resistance, and normal wear-and-tear by exposure to dirt, sun, liquids, food, sharp objects and other potentially damaging items.

The interlocking grid portion 170 can have a plurality of rectangles, a plurality of squares, a plurality of diamonds, a plurality of circles, or any type of design as long as the plurality of shapes are reinforced and interlocked with each other to provide the plurality of apertures through which any collected dust, debris, soil, dirt, or other small items at the bottom side 160 can fall while providing enough strength at the bottom side 160. The plurality of apertures within the interlocking grid portion 170 can be as small as 0.5 mm by 0.5 mm to as large as 5 mm by 5 mm depending on the purpose of the bag 100 used. For example, a bag 100 used for transporting sports equipment can have larger aperture sizes whereas a bag 100 used for traveling purposes can have smaller aperture sizes. The thickness of the interlocking grid lines may also vary depending on the use of bag 100. The thickness of the interlocking grid lines are higher if the bag 100 is regularly used for carrying heavy items whereas the thickness of the interlocking grid lines is lower if the bag 100 is used for carrying lightweight items. For example, the thickness of the interlocking grid lines is approximately in the range of 0.5 mm to 1 mm for providing higher tensile strength whereas the thickness of the interlocking grid lines is approximately in the range of 0.1 mm to 0.3 mm for providing lower tensile strength. None of these measurements are to be interpreted as limiting in nature since the measurements of the plurality of aperture sizes and interlocking grid lines are easily changeable depending on the type of bag produced.

As shown in FIGS. 5 and 6, the zipper 195 on the secondary opening 115 may have at least one or two zipper tabs 197 for accessing the secondary opening 115. For the bag 100 in FIGS. 5 and 6, two zipper tabs 197 are illustrated so that the zipper 195 can be easily opened by grabbing a first and/or a second zipper tab 197 to open the secondary opening 115. By grabbing and manually controlling the at least one or two second zipper tabs 197A-B, the bottom side 160 with the flap 165 can remain closed as shown in FIG. 6 during normal use or the bottom side 160 with the flap 165 can be completely open to expose the interlocking grid portion 170 for cleaning and aerating the bag 100.

During every day use for transporting internal contents within the bag 100 in the interior compartment 175, the flap 165 is typically closed on the bottom side 160 as shown in FIG. 6. The flap 165 in the closed position protects the contents within the bag 100 during transportation and every day use. The secondary opening 115 on the bottom side 160 is accessed by opening the flap 165 when a user desires to empty any dust, dirt, debris, soil and/or sand collected at the bottom of the bag 100. The duffel bag 100 can be held at the handles 125 to shake out any collected dust, debris, soil, dirt and/or sand from the bag 100 without having to take any of the contents out of the bag 100 through the primary opening 120 at the top 135 as is normally required to clean out collected crumbs, dirt, debris, soil and sand from the bottom of the bag 100. Moreover, the bag 100 can be vertically hung overnight with the flap 165 in an open or a semi-open position for drying wet items in the bag or aerating the bag 100 without removing any contents from the inside. With easy access to the interior compartment 175 of the bag 100, the bag 100 can be aerated and cleaned out on a regular basis without any hassle in an extremely efficient manner.

Referring to FIGS. 7-9, a second type of bag or tote bag 200 is illustrated that has a secondary opening 280 on a right side 240 of the bag 200. The tote bag 200 generally defines a top side 230, a bottom 255, a front side 205, a rear side 290, handles 225 attached at the front and rear sides 205, 290, opposing right and left sides 240, 250, a flap 265 covering the right side 240, a primary opening 220 at the top side 230, and a secondary opening 280A-B at the right side 240. The flap 265 on the right side 240 connects the front side 205, rear side 290, top side 230 and bottom 255 at the right proximal edge 245, right distal edge 247, right bottom edge 243, and at the top part of the flap 267.

FIG. 8 illustrates a side view of the tote bag 100 wherein the right side 240 of the tote bag 200 is shown with its front and rear sides 205, 290. The front side 205, rear side 290 and bottom side 260 (shown in FIG. 9) are joined along the edges by a flap 265 covering the right side 240. The side view of the tote bag 200 also illustrates the secondary opening 280A-B that is selectively opened or closed preferably using a zipper 295A-B located on the side edges of the right side 240. More particularly, the right proximal edge 245 and right distal edge 247 are shown to have the zipper 295A, 295B even though other types of closing and opening means can be utilized. The zipper 295A-B is shown to be closed on the right proximal edge 245 and right distal edge 247 located on each side edge of the flap 265 covering the right side 240. The secondary opening 280 is selectively closed or opened preferably by the zipper 295A-B that extends from the bottom 255 to the top side 230 at the right proximal edge 245 and the right distal edge 247.

The tote bag 200 has a holding means 287, shaped as a short and flexible handle attached on the edge of the top side 230, close to the top part of the flap 267. The tote bag 200 also has an opening means 285 that is also shaped as a flexible and short handle and located immediately below the holding means 287. The opening means 285 is attached on the zipper tab 297A of the right proximal edge 245 and on the zipper tab 297B of the right distal edge 247. Both the holding means 287 and opening means 285 are similar in shape and size and used to open the flap 265 covering the right side 240. The secondary opening 280 covered by the flap 265 may be opened by grasping the holding means 287 with one hand while the opening means 285 is pulled downwardly by holding the opening means 285 with another hand to closably open the flap 265 and zipper 295A-B as to pull the flap 265 away and downwardly from the bag 200. The zipper 295A-B extending both the right distal edge 247 and the right proximal edge 245 on the right side 240 allows any user to closably open and openly close the flap 265 completely from the right side 240 while the flap 265 remains permanently attached to the right bottom edge 243 as shown in FIGS. 8-9.

FIG. 9 illustrates the flap 265 on the right side 240 in an open position so that the interior compartment 275 of the tote bag 200 is shown. The interior compartment 275 is formed on the inside of the tote bag 200 in which various contents can be carried. As the primary opening 220 is selectively closed preferably using a zipper 220 for providing normal access to the interior compartment 275, the secondary opening 280 on the right side 240 is also selectively closed preferably using the zipper 295. However, the secondary opening 280 is not limited to just the zipper 295, but to any type of opening and closing means that performs the same functionality. The secondary opening 280, extending to the right proximal edge 245, right distal edge 247, and right bottom edge 243, that is selectively closed or opened preferably using the zipper 295A-B for providing access to the interior compartment, can be accessed from the right side 240. Even though the secondary opening 280 is located on the right side 240 for exemplary purposes, the secondary opening 280 is not limited to this particular side. The secondary opening 280 may be on the left side 250, the front side 205, the rear side 290, or the bottom side 260. The inside of the bottom side 260 is shown from the side view with the flap 265 in an open position.

During every day use for transporting internal contents within the tote bag 200 in the interior compartment 275, the flap 265 is typically closed on the right side 240 as shown in FIG. 8. The flap 265 in the closed position protects the contents within the bag 200 during transportation and every day use. The secondary opening 280 on the right side 240 is accessed by opening the flap 265 when a user desires to empty any dust, dirt, debris, soil and/or sand collected at the right side 240 of the bag 200. The tote bag 200 can be held at the left side 250 to shake out any collected dust, debris, soil, dirt and/or sand from the bag 100 through the right side 140 without having to take any of the contents out of the bag 200 through the primary opening 220 at the top side 230 as is normally required to clean out collected crumbs, dirt, debris, soil and sand from the bottom of the bag 200. Moreover, the tote bag 200 can be vertically hung overnight with the flap 265 in an open or a semi-open position for drying wet items in the bag or aerating the bag 200 without removing any contents from the inside. With easy access to the interior compartment 275 of the bag 200, the bag 200 can be aerated and cleaned out on a regular basis without any hassle in an extremely efficient manner.

Referring to FIGS. 10-11, the second type of bag or tote bag 200 from FIGS. 7-9 is illustrated that has a secondary opening 260 on a bottom 255 of the bag 200. Similar to the tote bag 200 of FIGS. 7-9, the tote bag 200 generally defines a top side 230, a bottom 255, a front side 205, a rear side 290, handles 225 attached at the front and rear sides 205, 290, opposing right and left sides 240, 250, a primary opening 220 at the top side 230, and a secondary opening 280A-B with a flap 265 covering the bottom 260. The flap 265 on the bottom 260 connects the front side 205, rear side 290, right side 240 and left side 250 at the left bottom edge 253, right bottom edge 243, front bottom edge 207, and rear bottom edge 293.

FIG. 11 further illustrates the flap 265 in an open position with the secondary opening 280 on the bottom 255 being completely open. The flap 265 at the bottom 255 is depicted as being attached to the rear side 290 at the rear bottom edge 293 while the zipper 295 extends from the left bottom edge 253, through the front bottom edge 207, and to the right bottom edge 243 for accessing the secondary opening 280.

Immediately beneath the flap 265 that basically covers the entire bottom 255, the interlocking grid portion 270 on the inner side of the bottom 255 is illustrated in FIG. 11. The interlocking grid portion 270 defining a plurality of apertures wherein the grid portion 270 is positioned on the interior side of the flap 265 and attached to the main body at the periphery of the secondary opening 280, for removing the collected dust and debris through the plurality of apertures while shaking the bag 200 after opening the flap 265. The interlocking grid portion 270 may be permanently attached to the main body at the periphery of the secondary opening 280 or removably attached to the main body at the periphery of the secondary opening 280 via a third fastening mechanism such as a zipper, hooks, snaps, velcro, or other similar means. The interlocking grid portion 270 is strong enough to support and retain the contents within the interior compartment 275 with the flap 265 being open while releasing any collected dust, debris, soil, dirt and other small items at the bottom 250 through the grid portion 270 with a plurality of apertures. The tote bag 200 can be held by the handles 225 or by the opposing right and left sides 250, 240 while shaking and releasing any collected dust, debris, soil, dirt and other small items through the plurality of apertures of the grid portion 270. The interlocking design allows the bag 200 to support any internal contents within the bag 200 in the interior compartment 275 while the flap 265 is held open and the bag 200 is shaken to release the collected dust, debris, soil, dirt and other small items through the plurality of apertures of the grid portion 270.

The interlocking grid portion 270 defining a plurality of apertures, the grid portion 270 is positioned on the interior side of the flap 265 and attached to the main body at the periphery of the secondary opening 280, for removing the collected dust and debris through the plurality of apertures while shaking the bag 200 after opening the flap 265. The interlocking grid portion 270 illustrated in FIGS. 7-11 is generally flexible and made from plastics so that the entire bag 200 may be folded and compressed when the bag 200 is not being used. The interlocking grid portion 270 is preferably made of high tenacity, high molecular weight, polyester yarns that are woven, reinforced in an interlocking grid design and further coated with polyvinyl chloride (PVC) for providing damage protection and durability for long-term and rigorous use of the tote bag 200 over a long period of time. The interlocking grid portion 270 can be made out of other similar materials such as nylon, vinyl, polymers, or synthetics as long as the material provides strength and durability to endure long-term and rigorous use of the bag 200 containing wet swim suits, heavy every day items, containers with liquids, and other similar items whether having a rigid or a flexible form. Other materials may be utilized to provide the same functionality. The coating of PVC can also be substituted with other types of thermoplastic polymers or plastics such as polyethylene or polypropylene to provide biological resistance, waterproof protection, chemical resistance, ultra violet resistance, corrosion resistance, and normal wear-and-tear by exposure to dirt, sun, liquids, food, sharp objects and other potentially damaging items.

The interlocking grid portion 270 can have a plurality of rectangles, a plurality of squares, a plurality of diamonds, a plurality of circles, or any type of design as long as the plurality of shapes are reinforced and interlocked with each other to provide the plurality of apertures through which any collected dust, debris, soil, dirt, or other small items at the bottom side 260 can fall while providing enough strength at the bottom 255. The plurality of apertures within the interlocking grid portion 270 can be as small as 0.5 mm by 0.5 mm to as large as 5 mm by 5 mm depending on the purpose of the bag 200 used. For example, a tote bag 200 used for recreational and leisure activities can have larger aperture sizes whereas a tote bag 200 used for traveling and everyday purposes can have smaller aperture sizes. The tote bag 200 used for going to the beach will only require sandals, beach towel, water bottles, clothing items, books and light weight items, whereas the tote bag 200 may be used for carrying heavier items such as laptops and files for everyday use. The thickness of the interlocking grid lines may also vary depending on the use of bag 200. The thickness of the interlocking grid lines are higher if the bag 200 is regularly used for carrying heavy items whereas the thickness of the interlocking grid lines is lower if the bag 200 is used for carrying lightweight items. For example, the thickness of the interlocking grid lines is approximately in the range of 0.5 mm to 1 mm for providing higher tensile strength whereas the thickness of the interlocking grid lines is approximately in the range of 0.1 mm to 0.3 mm for providing lower tensile strength. None of these measurements are to be interpreted as limiting in nature since the measurements of the plurality of aperture sizes and interlocking grid lines are easily changeable depending on the type of bag produced. As long as the interlocking design serves the functionality of enduring support of the inner contents, the dimensions of the interlocking design can be varied.

As shown in FIG. 11, the zipper 195 on the secondary opening 280 may have at least one or two zipper tabs 297A-B for accessing the secondary opening 280. For the bag 200 in FIGS. 10 and 11, two zipper tabs 297A-B are illustrated so that the zipper 295 can be easily opened by grabbing a first and/or a second zipper tab 297A-B to open the secondary opening 280. By grabbing and manually controlling the at least one or two second zipper tabs 297A-B, the bottom side 260 with the flap 265 can remain closed as shown in FIG. 10 during normal use, or the bottom side 260 with the flap 265 can be completely open to expose the interlocking grid portion 270 for cleaning and aerating the bag 200.

During every day use for transporting internal contents within the tote bag 200 in the interior compartment 275, the flap 265 is typically closed on the bottom side 260 as shown in FIG. 10. The flap 265 in the closed position protects the contents within the bag 200 during transportation and every day use. The secondary opening 280 on the bottom side 260 is accessed by opening the flap 265 when a user desires to empty any dust, dirt, debris, soil and/or sand collected at the bottom of the bag 200. The tote bag 200 can be held at the handles 225 or at the opposing right and left sides 250, 240 to shake out any collected dust, debris, soil, dirt and/or sand from the bag 200 through the plurality of apertures of the interlocking grid portion 270 without having to take any of the contents out of the bag 200 through the primary opening 220 at the top side 230 as is normally required to clean out collected crumbs, dirt, debris, soil and sand from the bottom of the bag 200. Moreover, the bag 200 can be vertically hung overnight with the flap 265 in an open or a semi-open position for drying wet items in the bag or aerating the bag 200 without removing any contents from the inside. With easy access to the interior compartment 275 of the bag 200, the bag 200 can be aerated and cleaned out on a regular basis without any hassle in an extremely efficient manner.

An interior compartment 375 is formed on the inside of the sports bag 300 in which various contents can be carried. As the primary opening 320 is selectively closed preferably using a zipper for providing access to the interior compartment 375, the secondary opening 380 on the right side 340 is also selectively closed preferably using a zipper 395A-B. However, the secondary opening 380 is not limited to just the zipper 395A-B, but to any type of opening and closing means that performs the same functionality.

FIG. 13 illustrates a side view of the sports bag 300 wherein the right side 340 of the sports bag 300 is shown with its front and rear sides 305, 390. The front side 305, rear side 390 and bottom end 355 are joined along the edges by a flap 365 covering the right side 340. The side view of the sports bag 300 also illustrates the secondary opening 380 that is selectively opened or closed preferably using a zipper 395A-B located on the side edges of the right side 340. More particularly, the right proximal edge 345 and right distal edge 347 are shown to have the zipper 395A, 395B even though other types of closing and opening means can be utilized. In FIG. 13, the zipper 395A-B is shown to extend to and to be closed on the right proximal edge 345 and right distal edge 347 located on each side edge of the flap 365 covering the right side 340. The right proximal edge 345 and right distal edge 347 with the zipper 395A-B eventually meet at the top portion so that the zipper 395A-B can close the entire right side 340. The secondary opening 380 is selectively closed or opened preferably by the zipper 395A-B that extends from the bottom 355 to the top side 330 at the right proximal edge 345 and the right distal edge 347 whereby they meet to completely close the flap 365 over the right side 340 and the right hand portion of the top side 330.

The sports bag 300 has a holding means 387, shaped as a short and flexible handle attached on the edge of the top side 330, close to the top part of the flap 365. The sports bag 300 also has an opening means 385 that is also shaped as a flexible and short handle and located immediately below the holding means 387. The opening means 385 is attached on the zipper tab 397A of the right proximal edge 345 and on the zipper tab 397B of the right distal edge 347. Both the holding means 387 and opening means 385 are similar in shape and size and used to open the flap 365 covering the right side 340. The secondary opening 380 covered by the flap 365 may be opened by grasping the holding means 387 with one hand while the opening means 385 is pulled downwardly by holding the opening means 385 with another hand to closably open the flap 365 and zipper 395A-B as to pull the flap 365 away and downwardly from the bag 300.

The interlocking grid portion 370 may be permanently attached to the main body at the periphery of the secondary opening 380 or removably attached to the main body at the periphery of the secondary opening 380 via a third fastening mechanism such as a zipper, hooks, snaps, velcro, or other similar means. The interlocking grid portion 370 beneath the flap 365 is strong enough to retain the contents within the interior compartment 375 with the flap 3645 being open while releasing any collected dust, debris, soil, dirt and other small items at the right side 340 through the grid portion 370 with a plurality of apertures. The bag 300 can be held by the handles 325 while shaking and releasing any collected dust, debris, soil, dirt and other small items through the plurality of apertures of the interlocking grid portion 370. The interlocking design allows the bag 300 to support any internal contents within the bag 300 in the interior compartment 375 while the flap 365 is held open and the bag 300 is shaken to release the collected dust, debris, soil, dirt and other small items through the plurality of apertures of the grid portion 370.

The interlocking grid portion 370 illustrated in FIGS. 12-13 is generally flexible and made from plastics so that the entire bag 300 may be folded and compressed when the bag 300 is not being used. The interlocking grid portion 370 is preferably made of high tenacity, high molecular weight, polyester yarns that are woven, reinforced in an interlocking grid design and further coated with polyvinyl chloride (PVC) for providing damage protection and durability for long-term and rigorous use of the sports bag 300 over a long period of time. The interlocking grid portion 370 can be made out of other similar materials such as nylon, vinyl, polymers, or synthetics as long as the material provides strength and durability to endure long-term and rigorous use of the bag 300 containing heavy sports equipment and other items of similar weight whether having a rigid or a flexible form. Other materials may be utilized to provide the same functionality. The coating of PVC can also be substituted with other types of thermoplastic polymers or plastics such as polyethylene or polypropylene to provide biological resistance, waterproof protection, chemical resistance, ultra violet resistance, corrosion resistance, and normal wear-and-tear by exposure to dirt, sun, liquids, food, sharp objects and other potentially damaging items.

The interlocking grid portion 370 can have a plurality of rectangles, a plurality of squares, a plurality of diamonds, a plurality of circles, or any type of design as long as the plurality of shapes are reinforced and interlocked with each other to provide the plurality of apertures through which any collected dust, debris, soil, dirt, or other small items at the right side 340 can fall while providing enough strength at the right side 340. The plurality of apertures within the interlocking grid portion 370 can be as small as 0.5 mm by 0.5 mm to as large as 5 mm by 5 mm depending on the purpose of the bag 300 being used. For example, a bag 300 used for transporting sports equipment can have larger aperture sizes whereas a bag 300 used for traveling purposes can have smaller aperture sizes. The thickness of the interlocking grid lines may also vary depending on the primary use of bag 300. The thickness of the interlocking grid lines are higher if the bag 300 is regularly used for carrying heavy items whereas the thickness of the interlocking grid lines is lower if the bag 300 is used for carrying lightweight items. For example, the thickness of the interlocking grid lines is approximately in the range of 0.5 mm to 1 mm for providing higher tensile strength whereas the thickness of the interlocking grid lines is approximately in the range of 0.1 mm to 0.3 mm for providing lower tensile strength. None of these measurements are to be interpreted as limiting in nature since the measurements of the plurality of aperture sizes and interlocking grid lines are easily changeable depending on the type of bag produced.

During every day use for transporting internal contents within the sports bag 300 in the interior compartment 375, the flap 365 is typically closed on the right side 340.

Alternatively, the sports bag 300 can be held by the handles 325 and the side handle 383 attached on the left side 350 to tilt the bag 300 and to shake out any collected dust, debris, soil, dirt and/or sand from the bag 100 through the plurality of apertures of the interlocking grid portion 370. Moreover, the bag 300 can be vertically hung overnight with the flap 265 in an open or a semi-open position for cleaning and aerating the sports bag 300 without removing any contents from the inside. With easy access to the interior compartment 375 of the bag 300, the bag 300 can be aerated and cleaned out on a regular basis without any hassle in an extremely efficient manner.

Referring now in detail to the drawing figures, FIGS. 14-16 illustrate a bag that also comprises a backpack 400 in accordance with the present invention. The backpack 400 generally defines a top side 430, a bottom side 460, a front side 405, a rear side 490 (not shown in FIGS. 14-16), opposing right and left sides 440, 450, a flap 465 on the bottom side 460, a primary opening 420 between the top side 430 and front side 405 that extends only top half, and a secondary opening 460 at the bottom end 455. The backpack 400 also includes shoulder straps 125 attached to the top and bottom edges of the rear side 490. The bottom side 460 of the backpack 400 with the flap 465 connects to the front side 405, rear side 490, right side 440, and left side 450 at the front bottom edge 407, rear bottom edge 457, right bottom edge 443, and left bottom edge 453. The backpack 400 may optionally have an external pocket 414 on the lower, front side 405 with a zipper handle 459 for opening the external pocket 414, and mesh compartments 412A-B on lower, right and left sides 450, 440 for carrying items externally. The backpack 400 also has a handle 425 at the top portion of the backpack 400 that is located between the top side 430 and rear side 490 extending axially only a small part of the top portion. Therefore, the backpack 400 can be carried by the shoulder straps 477 or by the handle 425.

An interior compartment 475 is formed on the inside of the backpack 400 in which various contents can be carried. As the primary opening 420 is selectively closed and opened preferably using a zipper for providing access to the interior compartment 475, the secondary opening 415 on the bottom 455 is also selectively closed and opened preferably using a zipper 495. However, the secondary opening 415 is not limited to just the zipper 495, but to any type of opening and closing means that performs the same functionality.

The interlocking grid portion 470 may be permanently attached to the main body at the periphery of the secondary opening 415 or removably attached to the main body at the periphery of the secondary opening 415 via a third fastening mechanism such as a zipper, hooks, snaps, velcro, or other similar means. The interlocking grid portion 470 illustrated in FIG. 16 is generally flexible and made from plastics so that the entire backpack 400 may be folded and compressed when the bag is not being used. The interlocking grid portion 470 is preferably made of high tenacity, high molecular weight, polyester yarns that are woven, reinforced in an interlocking grid design and further coated with polyvinyl chloride (PVC) for providing damage protection and durability for long-term and rigorous use of the backpack 400 over a long period of time. The interlocking grid portion 470 can be made out of other similar materials such as nylon, vinyl, polymers, or synthetics as long as the material provides strength and durability to endure long-term and rigorous use of the backpack 400 containing computers, books, files, and other items of similar weight whether having a rigid or a flexible form. Other materials may be utilized to provide the same functionality. The coating of PVC can also be substituted with other types of thermoplastic polymers or plastics such as polyethylene or polypropylene to provide biological resistance, waterproof protection, chemical resistance, ultra violet resistance, corrosion resistance, and normal wear-and-tear by exposure to dirt, sun, liquids, food, sharp objects and other potentially damaging items.

The interlocking grid portion 470 can have a plurality of rectangles, a plurality of squares, a plurality of diamonds, a plurality of circles, or any type of design as long as the plurality of shapes are reinforced and interlocked with each other to provide the plurality of apertures through which any collected dust, debris, soil, dirt, or other small items at the bottom side 460 can fall while providing enough strength at the bottom side 460. The plurality of apertures within the interlocking grid portion 470 can be as small as 0.5 mm by 0.5 mm to as large as 5 mm by 5 mm depending on the purpose of the bag 100 used. For example, a larger-sized backpack 400 used for military purposes can have larger aperture sizes whereas a backpack 400 used for every day use can have smaller aperture sizes. The thickness of the interlocking grid lines may also vary depending on the use of backpack 400. The thickness of the interlocking grid lines are higher if the backpack 400 is regularly used for carrying heavy items whereas the thickness of the interlocking grid lines is lower if the backpack 400 is used for carrying lightweight items. For example, the thickness of the interlocking grid lines is approximately in the range of 0.5 mm to 1 mm for providing higher tensile strength whereas the thickness of the interlocking grid lines is approximately in the range of 0.1 mm to 0.3 mm for providing lower tensile strength. None of these measurements are to be interpreted as limiting in nature since the measurements of the plurality of aperture sizes and interlocking grid lines are easily changeable depending on the type of bag produced.

As shown in FIG. 16, the zipper 495 on the secondary opening 415 may have at least one or two zipper tabs 497A-B for accessing the secondary opening 415. For the backpack 400 in FIG. 16, two zipper tabs 497A-B are illustrated so that the zipper 495 can be easily opened by grabbing a first and/or a second zipper tab 497A-B to open the secondary opening 415. By grabbing and manually controlling the at least one or two second zipper tabs 497A-B, the bottom side 460 with the flap 465 can remain closed as shown in FIG. 15 during normal use or the bottom side 460 with the flap 465 can be completely open to expose the interlocking grid portion 470 for cleaning and aerating the backpack 400.

During every day use for transporting internal contents such as a laptop and books within the backpack 400 in the interior compartment 475, the flap 465 is typically closed on the bottom side 460 as shown in FIG. 15.
